Publishing Website

after I did some changes in the source code I am trying to publish the source code using visual studio 2010 but for some reason I can't see any option to do so,
I have published several projects already using VS2010 and it was a pretty strait forward procedure.
after looking on the web, all I could find is guides about installing and deploying blogengine using web-matrix or some other platform but no way to publish from the source code itself.
how I can do this?
